Steps to reproduce: 1. create VM (kvm) 2. add bridged(?) VirtIO network or e1000(?) 3. start using internet from VM Actual results: Kernel panic (screenshoot in attach) Expected results: all works OK Additional info: when I;ve used e1000 driver for VM I've got this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1093708
Created attachment 134961 [details] Kernel panic screen
I can reproduce with VM with linux bridged rtl8139
Created attachment 135061 [details] Kernel panic screen with rtl8139 Sorry for screenshots. Dont have device to which I can forward panics.
